Professor Jose Martinez-Lorenzo Awarded $500K NSF CAREER Award March 6, 2017
ALERT Thrust R3 Project Investigator, Professor Jose Martinez-Lorenzo of Northeastern University was recently awarded a $500K National Science Foundation (NSF) CAREER Award for his work on developing a method for “4D mm-Wave Compressive Sensing and Imaging at One Thousand Volumetric Frames per Second.” Millimeter-wave sensing and imaging systems are generally used for a wide range of applications, such as security monitoring to detect potential threats at the airport and biological imaging for wound diagnosis and healing. Because this is the first four-dimensional millimeter-wave imaging system that can operate in quick-changing scenarios, it will benefit society greatly.
One of the main applications of this system is finding security threats hidden under clothing, inside backpacks, or in public spaces, such as sports arenas. The system can scan multiple people within 26 cubic meters and produce 1000 3D image frames per second. This far surpasses existing millimeter-wave sensing and imaging systems.
Despite the efficiency of this system, there are still some challenges to overcome. This project will look to address these challenges and ideally, the results of this research will establish the scientific basis for the proposed new sensing and imaging systems, by enhancing the imaging performance, reliability, and efficiency while reducing the hardware complexity, overall cost, and energy consumption of the system.
Additionally, Professor Martinez-Lorenzo will develop an educational program that combines classroom learning with research training methods to help students understand the principles and limitations of wave-based imaging. This educational program will also collaborate with the Northeastern University Cooperative Education and Career Development Program to transition students into industry and the Northeastern University Center for STEM Education to provide valuable research experiences for K-12, undergraduate, and underrepresented students, as well as education through online materials and public venues.
ALERT’s Methods to Improve the Detection of Hidden Explosives Wins Patent March 3, 2017
ALERT researchers, Prof. Carey Rappaport and Prof. Jose Martinez-Lorenzo of Northeastern University were awarded a patent for “Signal Processing Methods and Systems for Explosives Detection and Identification Using Electromagnetic Radiation” (U.S. Patent 9,575,045) on February 21, 2017.
This patent is for an algorithm designed to rule out non-explosive concealed foreign objects affixed to the skin (i.e. hidden under clothing). Current security screening systems, such as AIT Millimeter Wave Scanners used at airports to scan passengers, are able to identify items with distinct shapes that are hidden on the body, such as guns and knives. However, explosives are considerably more difficult to identify in this manner, due to the fact that the size and shape of explosives can vary greatly, leading to time-consuming and potentially dangerous security pat-downs to determine if a suspicious object is a security threat, or a wallet that a passenger forgot to place in the bin.
Prof. Rappaport and Prof. Martinez-Lorenzo believe their algorithm, when plugged into existing screening systems, will greatly reduce the number of false alarms, and thus, the number of pat-downs needed, leading to greater accuracy in threat detection and shorter security lines. The improved reliability would benefit many: passengers, airlines, and the Transportation Security Administration; and possibly lead to the expansion of AIT Millimeter Wave Scanners into everyday use, such as railway stations, sporting venues, and other soft targets.

Year 4 Program Review Highlights ALERT Student Involvement January 27, 2017
The ALERT Year 4 Program Review was held on January 11th & 12th at Northeastern University in Boston, Massachusetts. The purpose of this review was to evaluate the ALERT research portfolio at both the theme and project levels, as well as the Center’s education program, transition efforts, and industrial partnerships. Several graduate students from ALERT’s academic partner institutions presented at this year’s review on behalf of the research projects in which they are currently involved.
University of Rhode Island PhD candidates, Austin Brown and Kevin Colizza presented on ALERT research related to the characterization and safe elimination of explosives materials, which they conducted under the guidance of Dr. Jimmie Oxley. Research in explosives characterization and elimination is especially important to those in the Homeland Security Enterprise tasked with the detection, identification, and destruction of homemade explosives (HMEs), such as bomb squads, and other first-responders.
Purdue University M.S. candidate, Nick Cummock presented on ALERT research led by Dr. Steven Son and related to small-scale characterization of homemade explosives (HMEs). The specific compositions of HMEs are nearly limitless, so making accurate assessments of threats from these materials is challenging. This research project seeks to develop a small-scale experimental approach that will result in quicker and more cost-effective characterization of HMEs, leading to greater accuracy in modeling and prediction of explosives related threats.
University of Puerto Rico Mayagüez M.S. candidate, Amanda Figueroa presented on her research project led by Dr. Samuel Hernandez. This research project deals with the use of infrared spectroscopy (IR) in standoff mode and coupled to laser sources operating in the mid-infrared (MIR) to develop confirming orthogonal chemical sensors for detecting explosives residues on clothing, travel bags, personal bags, laptop bags/cases, skin, and other substrates.
Xiao Wang, another Purdue University student and PhD candidate, presented on ALERT research conducted under the guidance of Dr. Charles Bouman and Dr. Ken Sauer related to advanced baggage screening and automatic target recognition (ATR), which is achieved via algorithms and devices primed to recognize objects based on data obtained from sensors. This research project seeks to improve the detection of potential threats in scanned baggage and reduce the false alarm rate without compromising safety at airport security checkpoints, resulting in a reduction of security costs and an overall safer and smoother experience for passengers.
Northeastern University PhD candidate, Mengran Gou presented on ALERT research led by Dr. Octavia Camps and Dr. Mario Sznaier and related to video-based methods to identify and track potential threats in heavily crowded public spaces. Video-based methods have an enormous potential for providing advance warning of terrorist activities and threats. In addition, they can assist and substantially enhance localized, complementary sensors that are more restricted in range, such as radar, infrared, and chemical detectors.
In addition to the outstanding ALERT student presentations that took place at the Year 4 Program Review, the Center introduced four new research projects taking place at Boston University, Duke University, Purdue University, and the University of Notre Dame.

Student Spotlight: Christian Sorensen November 1, 2016
Christian Sorensen, a Ph.D. student in Mechanical Engineering at Purdue University, is our newest participant in the ALERT DHS HS-STEM (Homeland Security Science, Technology, Engineering, and Mathematics) Science and Engineering Workforce Development Program (SEWDP). Christian began his graduate program at Purdue this fall, and is working with ALERT researcher, Prof. Steven Son. His research project is focused on how to better predict the threat of characterized ammonium nitrate-based homemade explosives. When asked what he is most passionate about when it comes to his research, he stated, “I’m interested in the aspects that lead to tools or procedures for public safety, while also gaining the knowledge base necessary to study future threats and provide expert technical knowledge about current explosive hazards.”
Christian’s involvement in Homeland Security began when he served as a Team Leader of the Explosive Ordnance Disposal (EOD) in the U.S. Air Force, where he gained first-hand experience of explosives threats. After leaving active military duty, he then went on to attend the New Mexico Institute of Mining and Technology (NMT), to obtain a B.S. in Mechanical Engineering with the Highest Honors in 2015. After graduating, Christian worked as a post-baccalaureate research assistant at Los Alamos National Laboratory (LANL), where he eventually taught military EOD technicians various explosives detection techniques through LANL’s Advanced Home Made Explosives course.
Of his experience working with Christian so far, Prof. Son expressed that, “Typically graduate students that join my group have very little experience with explosives. However, Christian comes to our group with many years of experience in the Air Force, as well as a year of research experience at Los Alamos National Laboratory. His experience is proving to be to be a great benefit to our group. For example, he did a demonstration for my energetic materials combustion class based on what he learned at Los Alamos teaching first responders. We expect great things from Christian and very much appreciate his ALERT support.”
As for his future plans to work within the Department of Homeland Security enterprise, he would like to return to LANL to work on high explosive science with an emphasis on better understanding ‘non-standard’ explosives (i.e. those not used by the military or in the commercial sector), and says he would also like to reprise his teaching role for military EOD technicians.
